Trihalomethane Precursor Removal by Ozone and Ultraviolet Radiation
The research objectives were definition of trihalomethane formation potential (THMFP) reduction in groundwater matrix using ultraviolet radiation (UV) catalyzed ozone oxidation (UV/Ozone)....

Ground Water Treatment System Using UV/H2O2 at Sacramento Army Depot
Ground water beneath the Sacramento Army Depot (SAAD) is being extracted and treated as part of a ground water remediation program. The extraction system is achieving contaminant capture...

Going Where No Man Can Go
After the 1979 accident at Three Mile Island Unit 2 in Harrisburg, Pa., some areas of the reactor plant were too contaminated for workers to survey, much less clean. The article describes...

Tomorrow's Energy Today
If concerns about global warming, acid rain and air pollution continue to mount, replacements for fossil fuels�for a century the dominant power source in the U.S.�will be necessary to...

The Continuing Evolution of a Radioactive Material Transport System
The paper considers the evolution of BNFL's transportation system and those lessons learned and incorporated or being incorporated in the system as it continues to evolve....

Regulatory Considerations for Designing Surface Facilities for Yucca Mountain High-Level Waste Repository
This paper outlines U.S. Nuclear Regulatory Commission's (NRC's) key regulations applicable to U.S. Department of Energy's (DOE's) design...

Recent Results on the Effect of Gamma Radiation on the Durability and Microstructure of DWPF Glass
The effect of gamma radiation on the durability and microstructure of a simulated nuclear waste glass from the Savannah River Site has been carefully investigated. Three large pieces of...

High Level Waste Management at Sellafield
Reprocessing of irradiated nuclear fuel has been carried out at Sellafield since 1952, when reprocessing of fuel from the original UK air-cooled reactors began. In 1964 a second reprocessing...

Incident Solar Flux at Fixed Orientations
Optimal orientations are computed to maximize or minimize the incident solar flux onto surfaces on spacecraft at fixed attitudes. This analysis was motivated by a potential need to optimize...

Space-Based Control of the Climate
The expected global greenhouse warming of 2 ?C may be reversed by a space-based screen that intercepts 3% of the incident solar radiation. Space-based devices may also mitigate the ozone/UV...

Large Space Systems in Global Change Mitigation
Alternative courses of action are an important aspect of reacting to climate changes, including the greenhouse effect, and other environmental issues such as depletion of the ozone layer....

A Mission to Earth: Global Rural Electrification
No nation can long remain morally strong or economically competitive without an inner purpose. There are many noble projects but few which will both kindle the individual's...

Preliminary Assessment of the Power Requirements of a Manned Rover for Mars Missions
This paper presents the results of a preliminary study to determine the total mass and power requirements of a Manned Mars Rover. The primary power for the Rover is provided by a Nuclear...

Lunar Base Power Requirements, Options & Growth
A preliminary study of lunar base scenarios and associated power requirements has recently been completed. Minimum power levels of 50-100 kW are required for 'science-only'...

Power for Magma Electrolysis
This paper summarizes qualitative issues of electrical power distribution for near-term lunar facilities. The issues to be discussed were developed during a conceptual study of a Lunar...

The Optimum Dimensions of Radiative Spines
Radiative pin fins (spines) are important in conjunction with heat rejection systems for space applications. In the design of radiators for space applications, spines possessing minimum...

Implications of the New Radiation Exposure Limits on Space Station Freedom Crews
Spaceflight unavoidably increases the exposure of astronauts to natural ionizing radiation. Any increase in radiation exposure increases the risk of contracting cancer or inducing genetic...

Space Power Systems?Radiation: Energy Conversion
Pair production is a way to change a photon, a gamma particle, into matter or energy. It is found that if a photon of energy greater than 1.02 MeV strikes a foil containing a large number...

Mission to Planet Earth: The Quest to Save the Environment
The Mission to Planet Earth is a program designed to look at the earth as an integrated system. It is an internationally supported project. It was conceived because the current methods...

New Technologies for Unmanned Space Exploration
There could be no better time than now for the development and implementation of new technologies such as V.L.S.I. and optoeraseable storage. Creative inventions from new mathematical...
